Random observation and a heads up, the NOW Foods Vitamin D3 2000 IU softgels contain rice bran oil, while the 1K and the 5K versions use olive oil.

Yeah, I think digestive absorption would have a much lower upper limit given how sparse it would have been in the diets of most ancestral humans.

Well, given that sun exposure can get you 10,000 to 20,000 IUs in an hour, depending on your latitude, complexion & cholesterol level, I personally am not concerned.

I figure the transporters get saturated with relatively small amounts and that the excess may be harmful in some as yet unknown way. I wouldn't be surprised if 3000 3x a day resulted in the same serum level as 5000 all at once.

I take the NOW 2,000 IU for more flexibility.

That's interesting Travis. I don't get that it would make any difference, given that it is fat-soluble. Many docs prescribe a larger dose once a week. I take 6,000 IUs once a day, but if forget, I just double the dose the next day. I take mine early in the day.

Love the NOW 5,000. Took it all winter because there is little sun here in the Northeast in the winter months. I switched to the 1,000 this summer so I can adjust, depending on how much sun I am getting from day to day.

My doctor said my vitamin D levels were the highest they had seen this past December, around the high 70s if I recall, after switching to the 5,000 for a few weeks. She told me to keep on doing whatever I was doing.

I used it 1 x per day and got to 85 ng/ml during the wintertime, so it is what they say it is.

I think I'm going to do 3-4K this winter and break it up so that I'm not ingesting more than 1K with any one meal. I have no evidence for it, but I suspect that it's better to space it out.

Also take the NOW 5000mg purchased from Amazon, and am 30 weeks pregnant. My OB said my Vitamin D levels were among the best she has seen in quite awhile, and to continue my regimine. (Live in the Seattle area to boot)
